MEANS FOR IG NITING STREET OR OTHER LAMPS.

SPECIFICATIONforming part" of Letters Patent No. 778,139, dated December20, 1904.

Application filed August 25, 1903. Serial No- 170,690,

To all whom it may concern: I

Be it known that I, PIETER DIRK MUYLWYK,

I a subject of the Queen of the Netherlands, and

a resident of 76 Peperstraat, Gouda, Netherlands,- have invented anImproved Means for Igniting Street or other Lamps, of which I declarethe nature and the manner in which this invention is to be performed inthe following description.

This invention relates to means for lighting street or other lamps, moreparticularly incandescent gas-lamps, by means of a specialigniting-flame. i

The present; invention differs from the known devices of like nature byreason of the fact that in the present case by'manipulating thelighting-pole the principal and the igniting (or by-pass) flame arealternately set into and out of action by one operation.

In carrying the invention into effect the gaspipe of the lamp isprovided with a gas-cock having a slot or recess and. whichcommunicates, on the one hand, with the pipe leading to' the lamp-burnerand, on the other hand, with a tube of a type commonly known as anascending-flame igniter-tube, extending from the gas-cock casing up tonear the burner and by means of which the flame of the lightingpole usedfor turning the cock is communicated to the burner, so as to ignite thelampflame.

The igniting arrangement is illustrated in the annexed drawings, whichshow one form of this device-' Figure 1 illustrates the device, partlyin section and in connection with a burner. Fig. 2 is a side elevation,and Fig. 3 a longitudinal section, of the arrangement with the plug ofthe cock removed. Fig. 4: is a view of the cock-plug.

The gas-pipe a of the lamp does not lead direct to the burner,but isconnected with a cockcasingl), which is provided with three passages d ef, communicating with the bore of the cock-plug c. Passage d isconnected with the Passage 6 communicates with the pipe 9, which isconnected at one end to the cock-casingand at the other to the burner,and passage f communicates with an ascending-flame igniter-tube it,carried by the cockcasing. The igniter-tube it is preferably arranged sothat its lower end is placed close above the cock 0 and extends with itsupper end terminating in a small nozzle 7; up 'to near the burner. Thecock-plug c, which is held in position by the nut Z and the screw m, isprovided with an axial bore and has an external recess n, by means ofwhich the passage cl can be made to communicate, on the one hand, withthe passage 6 and, on the other hand, with the passage f. At one of itsends the cock-plug 0 is provided with one or several slots or notches 0,into which suitably-formed catches or projections of the lighting-poleused for turning the cock can be inserted. The extent of its revolution.can be limited by means of the screw no bearing against the cock-casing.

The manipulation of the device is as follows: The lighting-pole,provided with a lightingflame at its upper end and fitted with a catchor projection fitting into the slot 0 on the cockplug, is introducedinto the axial bore of the cock-plug c. By turning the cock-plug to theright the recess 47/ is placed over the three passage-orifices d e f.Consequently gas will flow from the gas-pipe a into the pipe g, leadingto the burner, as well as into the ignitertube 72. Some of the gasentering the igniterand ignites on the flame of the lighting-pole,

which issues through the upper aperture of the bore in the cock-plug.The flame thus ignited on the outer surface of the ignitertube ascendsalongthe series of holes and tube issues from the holes is arranged init the same direction the orifice ofpassage f is closed, leavingpassages d and 6 only connected with the recess 11, and cutting off thegas-supply to the igniter-tube. Any further turning of the plug isprevented by the screw m bearing against the cock-casing. To extinguishthe burner-flame, the cock-plug is turned in the opposite direction,whereby the passages cl 6 f are shut off. The position of the slot 0 onthe cock-plug will show whether the plug is turnedback sufliciently toshut OR the admission of gas.

The device is arranged on the bottom of the lantern, so that theigniter-tube is inside the lamp to prevent extinction of theignitingflame by wind or other causes.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare whatI claim is 1. An igniting device for gas-burners comprising a gas-supplypipe for the burner, an ignition-tube extending to the burner and havinga series of perforations distributed along its length, a valve andcasing controlling the gas-supply, said casing having passagescommunicating respectively with the upper and lower sections of thesupply-pipe and in substantial longitudinal alinement with each otherand also having a passage connecting with the ignition-tube located toone side from said other passages, the valve having a recess adapted tojoin all of said passages.

2. An igniting device for gas-burners comprising a casing having alinedopenings for the reception respectively of the gas-supply pipe and theburner-pipe, and a valve-receiving opening located to one side therefromand connecting with said rape-receiving openings by lateral passages,said casing also having an opening for the reception of an ignitertubeand a passage connecting said opening with the valve-receiving opening,and the valve fitting within said opening and having a peripheral recessadapted to control the passages to the various pipes.

3. The combination with a gas-burner and its supply-tube, of anignition-tube extending upwardly to within the burner, and a valve forcontrolling the supply of gas to the burner and ignition-tube, saidvalve having a flaring or coned hollow opening downwardly for thereception of a lighting-torch and means for engagement by said torch toturn the valve.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
